I have heard many people talk about document cameras. I always thought, “Yeah that’s nice, but I can do the same thing scanning documents with my SmartBoard.” Well I have spent this week in professional development learning about Best Practices in Mathematics. And finally I get it! I need (read need, not want) a document camera. Gone should be the days when we have students go up to the board and copy their work from their papers. What a waste of time, one. Two, you miss some of the learning in translation from paper to board. I get it now. Now hopefully I will get a document camera too.
